搜索方向 direction of search
- 该算法允许搜索方向有相对较大的误差,且不要求迭代点的可行性。
This algorithm allows the search direction with only moderate accuracy, and does not require the feasibility of the iteration points. - 在片间预测中,通过对光线空间片的纹理统计,确立初始的搜索方向,实现分层的直线方向搜索方法。
By adopting texture statistics for ray-space slice, initial search direction was established, and then multi-layer rectilinear direction search method was realized in inter-slice prediction. - 通过将问题的KKT系统转化成一个约束方程,算法在每步迭代只需解一个线性方程组即可得到搜索方向。
By reformulating the KKT system as a constrained equation, the algorithm generates the search direction by solving a linear equation at each iteration.
